CASTRO VALLEY -- A woman was found dead in a Castro Valley home Friday in what police are describing as a homicide.

A person inside the home in the 1900 block of Stanton Avenue called police around 4 p.m. to report the incident. Minutes later, deputies from the Alameda County Sheriff's Office found the woman dead inside the house, said Deputy April Luckett.

Luckett would not discuss the victim's injuries, but said the woman's death is being investigated as a homicide. Her identity was not released.

It is the first homicide this year in Castro Valley, which the sheriff's office patrols.
